It couldn't be analysed chemically because it's chemical composition is to complex. It would be hard for us to analyse them because once it has been removed from the organism, it ends as protoplasm only.
Geologists have divided the earth history into time units that are largely based on the earth's biotic composition. The modern geological time scale includes both relative and absolute age dating and represents the most up-to-date assessment of the earth's history.
In the modern geological time scale, the eras in earth's history when the planet was populated with advanced life forms are referred to as the Paleozoic (meaning ancient life), the Mesozoic (meaning middle life), and the Cenozoic (meaning recent life).
The correct answer is: B) H2O
Non-cyclic photophosphorylation is a light reaction and it occurs in the thylakoid membrane and it involves two different chlorophyll photosystem.
Non-cyclic photophosphorylation is a reaction where a water molecule is broken down into 2H+ + 1/2 O2 + 2e− . This process is called photolysis. The 2H+ and 1/2O2 from the water are left out for further use, while two electrons are kept in photosystem II.
Answer:
Continental crust is typically 40 km (25 miles) thick, while oceanic crust is much thinner, averaging about 6 km (4 miles) in thickness. The effect of the different densities of lithospheric rock can be seen in the different average elevations of continental and oceanic crust.
